A kinetic investigation of the thermal rearrangement of allyloxytetrazoles to N-allyltetrazolones, Journal of the Chemical Society, Perkin Transactions 2, 3, 489-494, 1997.0300-9580AUT: MCR00716;http://hdl.handle.net/10400.1/4256The mechanism of the thermal rearrangement of 1-aryl-5-allyloxytetrazoles 1 to give 1-aryl-4-allyltetrazolones 2 in very high yield has been investigated through kinetic studies in one polar and one less polar solvent. The results suggest mainly a concerted [3,3] sigmatropic process, in which a partially positively charged allyl group migrates from oxygen to nitrogen, similar to the polar transition state found in the Claisen rearrangement.engjournal article2014-06-05
